However, when I press ESC to return from full screen the launch and global menu bars get invisible, and I need to press super key (for example) to get them back. This situation is observed with any applications (e.g., chromium , document viewer). This didn't happen in the previous ubuntu version, but it is happening now in Ubuntu 13.10.
